METALLIC SHEET.

Application led October 29, 1925.

My invention relates to soft, pliable, me

tallic sheets capable of being ixedly attached to a material surface by means of heat and pressure.

The object of my invention is a process for producing a soft, pliable metallic sheet, such as old, silver, bronze or other substance, W ich may be fixedly attached to a material, such as a fabric, by means of heat 1o and pressure, resulting, in a compounded material of a soft, pliable nature from which the metallic sheet can not be separated by use, a further object of my invention being the products produced by my process.

It is evident that artistic and valuable results can be obtained if such metallic sheets can be fixedly attached to fabrics with the retention of softness and pliability, and that this value can be enhanced if the method of application is one which can be easily performed without the employment of intricate and expensive machinery.

My device has all of the above mentioned and other valuable features, in that it can be fixedly attached to fabrics b means of heat and pressure, such as may obtained from a heated flat iron.

It is evident that this means of attachy3b ment will enable the user to cut out any desiredshapes of the metallic sheets and to arrange them in any desired design, the thus formed design being fixedly attached to the fabric by appl ing a heated iron.

v I have foun that these desirable qualities of pliabilty and ease of application can be obtained from a thin pliable metallic foil having attached to its face a film of rubber, such attachment being accomplished by a pliable binder such as gun-cotton or other suitable material.

I have found it advantageous al:y times to add softening agents such as glycerine and gum and I prefer lto use these although I do not limit myself to their employment.

In Figure 1, 1 represents the gelatine glycerine and gum arabic mixture, 2 represents the foil of metallic material, 3 represents the solution of gun-cotton, gums and camphor, and 4 represents the india rubber and wax.

In Figure 2, 2 represents the foil of'metallic material, 3 represents the gun cotton,

ims and camphor and 4 represents the india rubber.

Serial No. 65,694.

I give the following as examples of modified methods of carrying out my process.

l. I. make a weak aqueous solution of gelatine, glycerine and gum arabic and pour it into a shallow flat dish and when it has evaporated to a thick consistency, I place a foil of metallic material, such vas sheet gold or sheet silver, thereon, allow to almost dry, remove the foil with the attached film, dry and press. I then produce an acetone solution of gun-cotton. gum copal, gum sandarac and camphor and apply a thin sheet of this solution, preferably by means of a brush, to the coated side of the metallic foil, and dry. I then appl a thin foil of india rubber and wax disso ved in carbon tetrachloride to the treated vside of the metallic foil and dry. I prefer to apply pressure during the last treatment in order to make a uniform film sheet and to produce adherence between the rubber sheet and the treated side of the metallic foil.

2. I dissolve rubber` in carbon tetrachloride, fiow it into a thin sheet and dry. To one side of this, I then apply a thin coating, or film, of gun-cotton, gum copal, gum sandarac and camphor dissolved in acetone, and when nearly dry, I place a thin metallic foil to the prepared side, a sheet of tissue paper over the metallic sheet, apply gentle and uniform pressure and dry.

It will thus be seen that my device comprises a thin metallic foil to one face of which is attached a film of gun-cotton and gums, and to this latter film is attached a thin film of rubber.

If, now, this device be placed upon a material, such as fabric, with the rubber side in abutment with the material, and heat and pressure be applied to the exposed surface, as, for instance by means of a hot iron, the rubber becomes soft. and permanently affixed to the material, thus presenting, in the case of a fabric, a soft, pliable material havifng a permanently aiiixed metallic face surace.

I do not limit myself to the particular number, materials, times, temperatures or steps of procedure as particularly men-A tioned herein, as these are given simply as a means for clearly describing my invention.

What I claim is 1. As an article of manufacture a soft, pliable metallic sheet capable of being lixedly attached to a material surface by means of heat and pressure comprising a soft, pliable metallic oil a film of un-cotton attached thereto and a film o rubber attached to the first mentioned lm.

2. As an article of manufacture a soft, pliable metallic sheet capable of being fixedly attached to a material surface by means of heat and pressure comprisin;Y a thin sheet of elatine attached to one ace of a soft, pliale, metallic foil, a thin film of gun-cotton attached to the face of the gelatine sheet and a thin film of rubber attached to the gun-cotton film.

3. As an article of manufacture a soft, pliable metallic sheet capable of being 'xedly attached to a material surface by means of heat and pressure comprising a thin sheet of gelatine and glycerine attached to one face of a soft, pliable, metallic foil, a thin film of gun-cotton attached to the face of the gelatine-glycerine sheet and a thin film of rubber attached to the guncotton iilm.

4. As an article of manufacture a soft,

pliable metallic sheet capable of being ixedly attached to a material surface by means of heat and pressure comprising a thin sheet of gelatine, glycerine and gum attached to one face of a soft, pliable, me-

tallic foil, a thin film of gun-cotton attached to the face of the gelatine-glycerineum sheet and a thin film of rubber attache to the gun-cotton film.

5. As an article of manufacture a soft, pliable metallic sheet capable of being tixedly attached to a material surface by means of heat and pressure comprising a thin sheet of gelatine, glycerine and gum,
